Q: The giant huntsman spider is so big it even took the trouble to have a size descriptor built into its name (given that Goliath was taken). The huntsman is neck and neck, or leg and leg, with the Goliath bird-eater for the title of biggest spider, by leg-span (in sheer body mass, though, the Goliath is more like an offensive lineman, while this spider is a lanky cornerback). A giant huntsman's legs can stretch out to 12 inches, and its speedy, crab-like gait makes it a fast hunter that excels at chasing down its meals. It hails from caves in Laos.

 The Brazilian salmon pink bird-eating tarantula has a leg-span that can reach 11 inches and weight that can tip the scales (well, for a spider) at about 3.5 ounces. Despite its name, it's not confirmed that they actually eat birds any more than do the Goliath bird-eaters. Instead, they dine on insects or the random small amphibian or reptile. Instead of making a web, it takes its prey by quick-strike ambush in the open. Bat-Eating Spiders Are Everywhere 
  
 Meet the golden-silk orb weaver spider. Step into its parlor, if you must. Don't be fooled by its deceptively gentle-sounding name. The female golden-silk orb weaver's body alone can reach 2 inches, its legs can stretch to more than 5 inches, and it's even been observed killing and eating tree snakes. What's more, a study published earlier this year found that these spiders, when living in urban areas, are growing even bigger than usual. Interesting side-note: The golden-silk orb weaver also belongs to the oldest surviving genus of spiders, Nephila , which has a fossil in the record that dates to 165 million years ago.

 Not to be outdone is a spider that's been making a big splash of late, with an entomologist's blog about his encounter with one . It's called the Goliath bird-eater (a.k.a., Theraphosa blondi ). It can weigh in at almost 6 ounces and it's been known to reach nearly a foot in leg-span. The "bird eater" moniker must be there to warn birds away, though, because this spider doesn't typically eat birds as a matter of, er, course. It will regularly eat small land animals such as frogs, lizards, and snakes, however. Spiders Have Personality Too 
  
 You almost feel for them, spiders. They can't help being what they are, and yet almost no one is happy to see them. Especially true when they have exceedingly long legs, thick bodies and a general mien that makes you turn quickly in some other direction. Photos don't bite, though, so let's take a look at some honking-big spiders -- with Halloween on the way, we may as well get started freaking ourselves out. Shown here is the Brazilian wandering spider (a.k.a. Phoneutria ), a feisty and venomous crawler from South America. Just four years ago it took home an award from the Guinness World Record people for the title of "most venomous" spider. This spidey's legs can span nearly 6 inches, its body just shy of 2 inches. It gets its name thanks to its preference for strolling along the tropic floor at night seeking out prey, rather than building webs or hiding out someplace waiting to strike. During the day, it lays low wherever it's convenient -- even inside banana plants, which is how it get its nickname "banana spider." NEWS: Puppy-Sized Spider Romps In Rainforest 
  
 For male wolf spiders, mating is all about the leg tapping. Much like the rhythmic peacock spider, a musically inclined male wolf spider can impress a female with his precisely choreographed series of leg taps. 
  
 Or, he can steal another male’s routine. New research published in the journal Animal Behavior shows that the brush-legged wolf spider is a master eavesdropper. 
  
 Giant Spiders to Freak You Out: Photos 
  
 Researchers raised a group of wolf spiders in a laboratory setting, where the tiny creatures weren’t exposed to any mating behaviors. When the laboratory spiders saw videos of wild males’ leg tapping routines, they unexpectedly emulated and mastered the behavior in as little as four days. 
  
 “There’s a lot of eavesdropping that occurs in the natural world, but it’s usually associated with more highly social animals with much bigger brains,” co-researcher George Uetz, a University of Cincinnati professor of biological sciences, explained in a news release. “It’s very common in birds, fish and mammals, but infrequently seen among invertebrates.” 
  
 Perhaps it’s for the better that male spiders take some cues from their competition: a nonplussed female will eat her suitor, making the mating game a matter of life and death.

Video provided by George UetzWhen it comes to courting, one common spider species is quick to learn, and that learning process involves eavesdropping on the visual cues of rivals to win their mate. The latest discovery in a research partnership represented by Alma College, The Ohio State University at Newark and the University of Cincinnati is the featured article in the August issue of the international research journal Animal Behaviour. Previous studies by the researchers explored how brush-legged wolf spiders (Schizocosa ocreata) used visual eavesdropping to try to outdo a male rival’s leg-tapping mating moves in the wild. In the great outdoors, the males start their show when they smell the pheromones in the silk of a ready-to-mate female.However, the researchers discovered that courtship behavior becomes a learning experience for male wolf spiders raised in the lab, and they pick it up quickly. When they were shown videos of other leg-tapping, courting males paired with silk cues from females, they quickly learned to recognize the behavior as part of the courtship process – in as little as four days. Having learned this connection between courtship of others and the presence of a female, the eavesdroppers then began courtship themselves.“This discovery has completely changed our way of thinking about this little spider,�? says co-researcher George Uetz, a University of Cincinnati professor of biological sciences. “We thought because they were invertebrates with a tiny brain, everything about them is genetically regulated in a hardwired nervous system, i.e., they respond instinctively because it’s programmed into their nervous system. Over the years, we’ve found there’s a lot more to the story. Males learn to associate the courtship behavior of other males with female cues and they can make this leap. It’s a complex set of behaviors for a tiny little brain. Not only do they learn from visual cues but also from vibration cues.�?Uetz adds that sexual selection in mating behavior is an important paradigm in evolutionary biology and is also studied in humans. Research into animal behavior also can provide insights into how human physiology or neurobiology works, says Uetz, although spiders navigate a completely different sensory world from humans.“There’s a lot of eavesdropping that occurs in the natural world, but it’s usually associated with more highly social animals with much bigger brains,�? says Uetz. “It’s very common in birds, fish and mammals, but infrequently seen among invertebrates.�?Meanwhile, as the male spiders perform their mating dance, the female is sizing them up to consider whether they’re worthy mating material. If they don’t pass inspection, she’ll try to eat her suitor. Uetz adds that about 12 percent of the males that successfully mate still get eaten.“Courting in response to other males’ signals is not without risks to the eavesdroppers,�? says co-researcher David Clark, an Alma College professor of biology. “The conspicuous courtship signals intended for females may also make males more visible to predators, like toads or birds searching for their next meal.�?Uetz says the particular species of wolf spiders studied are found over the eastern half of the U.S. and Canada. The research was conducted in the field in Cincinnati and in the labs at Alma College and the University of Cincinnati, with spiders collected from the Cincinnati Nature Center. The research was supported by National Science Foundation grants IOS-1026817 (D.L.C.) awarded to Alma College and IOS-1026995 (G.W.U.) awarded to the University of Cincinnati.Authors on the study are David Clark, a professor of biology at Alma College; Corinna Kizer Zeef, Gabriel Sabovodny and Aaron Hollenberg, undergraduate students at Alma College; J.

It doesn't take much observational power to note that spiders have tiny brains. Really tiny. So the recent finding out of the University of Cincinnati—that they learn how to court mates by eavesdropping on the competition—is all the more impressive. "It’s a complex set of behaviors for a tiny little brain," says biologist George Uetz of the brush-legged wolf spider his team studied in a lab, noting that the discovery "has completely changed our way of thinking about this little spider." Discovery News explains that mating is "all about the leg tapping" for these spiders, who try to wow females with a distinct series of taps. The spiders are found in the eastern US and Canada, but researchers used lab-raised ones who hadn't witnessed mating rituals in their experiments. Reporting in the journal Animal Behaviour, researchers say that when the spiders were shown videos of wild males tapping their legs to court females, the lab-raised ones could mimic and even master this behavior—and in just a matter of four days. "We thought because they were invertebrates with a tiny brain, everything about them is genetically regulated in a hardwired nervous system, ie, they respond instinctively because it's programmed into their nervous system," says Uetz. Instead, "Not only do they learn from visual cues but also from vibration cues." Quickly picking up on what's going on is a good thing, as mating is a risky business for these guys. If the tapping doesn't impress the female, she'll try to eat the male. Even among males that successfully court their females and mate, up to 12% are still eaten anyway.
